Description
Summary:This paper introduces a compact SPICE model of a two-terminal memory with a Pd/Ti/IGZO/p<sup>+</sup>-Si structure. In this paper, short- and long-term components are systematically separated and applied in each model. Such separations are conducted by the applied bias and oxygen flow rate (OFR) during indium gallium zinc oxide (IGZO) deposition. The short- and long-term components in the potentiation and depression curves are modeled by considering the process (OFR of IGZO) and bias conditions. The compact SPICE model with the physical mechanism of SiO<sub>2</sub> modulation is introduced, which can be useful for optimizing the specification of memristor devices.
